In enzymology, a homospermidine synthase (spermidine-specific) (EC 2.5.1.45) is an enzyme that catalyzes the chemical reaction
- spermidine + putrescine sym-homospermidine + propane-1,3-diamine
Thus, the two substrates of this enzyme are spermidine and putrescine, whereas its two products are sym-homospermidine and propane-1,3-diamine.
This enzyme belongs to the family of transferases, specifically those transferring aryl or alkyl groups other than methyl groups. The systematic name of this enzyme class is spermidine:putrescine 4-aminobutyltransferase (propane-1,3-diamine-forming).
